. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. Stratiomyiidae. 27 spot obcordate with a very fine middle line. Thorax shining black, slightly bluish; pubescence light yellowish, sometimes more greyish: humeral callus and a stripe from the callus to the wing-root white, the stripe considerably broadened behind: the callus is larger and the stripe is broader than in pantherinus. Abdomen white, the base witli a black spot, produced almost to the middle of the second segment, fourth segment with a black transverse band at the front margin, nearly reaching the side margins, fifth segment black with the hind margin pale. The spot on the fourth segment varies a good deal in form, it is as a rule excised in the middle of the hind margin, some- times including a white spot on each side, these spots may be con- nected with the white hind margin, or the band may be quite dis- solved in three spots; sometimes there is a small black spot on each side on the third segment, and finally this segment may bear a little black spot in the middle at the front margin. Venter black with the front margin of the second and the hind margins of the third, fourth and fifth segments white, these margins may be broad in the middle, and the white front margin of the second segment may be enlarged to a subquadratic spot, reaching the hind margin. Femora brownish. Fig. 10. Wing of N. uliginosns. black, with the tips broadly white, tibiae and tarsi white, hind tibiae brownish black in the middle, anterior tibiae slightly darkened. AVings hyaline with white veins, stigma light yellowish. Halteres white, the peduncle slightly darkened. Female. Front broad, snout moderately long, shorter than in pantherinus, antennae inserted nearly in the middle: above the an- tennae two oblique white stripes, going from the eye-margin to the base of the antennae, and nearly meeting in front. Eyes nearly round, not longer than high. Thorax with shorter, somewhat depressed pubescence.
